Security Software Engineer | AI Infrastructure Startup

A rapidly growing, venture-backed AI infrastructure company is seeking a highly technical Security Software Engineer to build and own security from the ground up.

This is a rare opportunity to join a founding-level engineering team working at the intersection of security, infrastructure, and artificial intelligence. The company partners with leading AI organizations to support large-scale data creation, model development, and agentic workflows, requiring innovative approaches to securing highly sensitive systems and data.

What You'll Do

  • Design and implement security infrastructure across AWS and GCP environments
  • Build automated systems for threat detection, incident response, and security operations
  • Secure AI-specific data pipelines, model interaction layers, and training workflows
  • Integrate security controls directly into engineering workflows without slowing development velocity
  • Contribute to core infrastructure and platform engineering initiatives beyond security
  • Establish and execute the company's security roadmap while helping define long-term security strategy

What We're Looking For

  • 4–7 years of experience in security engineering, infrastructure engineering, or related fields
  • Strong software engineering skills with Python, Go, and/or TypeScript
  • Experience securing cloud-native environments in AWS and/or GCP
  • A builder's mindset—someone who develops security systems and automation rather than relying solely on commercial tools
  • Ability to thrive in a fast-paced startup environment with significant ownership and autonomy

Why This Role?

  • Founding-level impact and visibility
  • Work on cutting-edge AI infrastructure challenges
  • Join a highly technical, talent-dense engineering team
  • Significant equity upside and competitive compensation
  • Opportunity to define security practices at a company experiencing rapid growth

If you're passionate about building security systems that protect next-generation AI platforms and want to have a direct impact on a company's trajectory, I'd love to connect.
